Developing a Method for Measuring Emission
Fluxes From Unconventional Natural Gas Extraction:
An Overview of The Garfield Country Study

Andrea Clements

      In recent years, the demand for natural gas has increased and with it has come an increase in extraction and production activities in tight sand and shale formations that require the use of hydraulic fracturing to stimulate natural gas production.  Many human health and environmental concerns are associated with these operations including impacts to land, water, air, human health, and wildlife as well as community nuisance issues.  Many of these concerns, especially in terms of air, are not presently well defined and the impacts on air quality are often some of the most difficult to quantify.  Operators, regulators, and communities all benefit from additional knowledge regarding the air emissions that results from drilling and production operations.

      This presentation will give an overview of our ongoing study in Garfield County, CO where we are working to measure the flux of various VOCs, including ozone precursors and air toxics, being emitted from the drilling, fracking, and flowback stages of new well development.  This will include a discussion of the involvement and collaboration of operators and the community in the development of this project, an overview of the methods being used, and a summary of some method validation work.
